My server goes from starting to stopping and I don't know why. I've tried to reinstall the modpack several times and to create a new world but nothing works. I was having this issue a long time ago and it was fixed by writing /fml confirm in the console but know it doesn't ask me to confirm anything. The modpack i'm using is Enigmatica 2
Here is my latest logg

I now think is my modpack causing the problem. I tried making a vanilla servber and that worked fine. The modpack had an uppdate today (or yesterday) so I might just have to wait untill they fix it.
